Technical Field

[0001] The utility model relates to the technical field of pile foundation positioning, and particularly relates to a stable pile foundation positioning device. Background Art

[0002] Pile foundation positioning devices are mainly used to ensure the accurate placement of components such as casing pipes and steel reinforcement cages during pile foundation construction, prevent inclination and deviation, and thus improve the overall quality of the pile foundation. In the prior art, there are various forms of pile foundation positioning devices, including but not limited to mechanical positioning devices, electronic pile driving positioning devices, and positioning devices specifically for steel casing pipes in bridge pile foundation construction. Mechanical positioning devices usually use components such as positioning arc plates and limit rods to position and fix pile foundation components through manual or mechanical adjustment methods. Electronic pile driving positioning devices use electronic devices such as sensors and controllers to achieve precise control of pile driving depth through real-time monitoring and feedback.

[0003] Sometimes the position where the pile foundation needs to be set is not flat enough, and it is necessary to manually adjust the angle of the pile foundation positioning device. Moreover, the existing pile foundation positioning devices cannot well find the vertical position, which makes the operation troublesome. For this reason, we propose a stable pile foundation positioning device to solve the above problems. Content of the Utility Model

The pile foundation positioning device can be fixed to the ground through fixing nuts and a fixing mechanism, and the guiding sleeve can be controlled to be in a vertical direction. The position of the pile foundation can be conveniently guided through the guiding sleeve and the guiding funnel, so that the pile foundation will not deviate to other positions. The vertical position can be determined through the horizontal positioning mechanism, which is convenient for the installation of the fixing mechanism. The collision between the pile foundation and the guiding sleeve can be reduced through the guiding wheel, and the pile driving deviation can be limited according to pile drivers with different diameters.

[0005] To achieve the above purpose, a stable pile foundation positioning device is provided, which includes a fixed bottom plate.

Embodiment

[0022] Refer to Figures 1 to 4 , an embodiment of a stable pile foundation positioning device of the present utility model includes a fixed bottom plate 1. Fixed nuts 2 are fixedly connected to the upper sides of the four corners of the fixed bottom plate 1. The fixed nuts 2 are threadedly connected to a fixing mechanism 6. A guide sleeve 3 is fixedly connected to the upper side of the middle of the fixed bottom plate 1. A guide funnel 4 is fixedly connected to the upper side of the guide sleeve 3. A guide wheel fixing frame 5 is fixedly connected to the outer wall of the guide sleeve 3. A guide wheel 8 is threadedly connected inside the guide wheel fixing frame 5. A horizontal positioning mechanism 7 is fixedly connected to the front outer wall of the guide sleeve 3. When installing the pile foundation, first, the pile foundation positioning device is horizontally installed through the horizontal positioning mechanism 7 and the fixing mechanism 6. Then, the pile foundation is guided into the guide sleeve 3 through the guide funnel 4. The guide funnel 4 facilitates the positioning of the pile foundation. Among them, the guide wheel 8 reduces the collision between the pile foundation and the guide sleeve, protecting the device.

[0023] The fixing mechanism 6 includes a conical positioning head 601, a first threaded rod 602, a rotating disk 603, and a rotating grip 604. The first threaded rod 602 is threadedly connected inside the fixing nut 2. The conical positioning head 601 is fixedly connected to the lower side of the first threaded rod 602, the rotating disk 603 is fixedly connected to the upper side of the first threaded rod 602, and the rotating grip 604 is fixedly connected to the upper side edge of the rotating disk 603. By rotating the rotating grip 604 to rotate the rotating disk 603 to reduce resistance, the first threaded rod 602 is driven to rotate in the fixing nut 2, and the conical positioning head 601 is driven into the ground. Different fixing mechanisms 6 are not connected, and they are driven into different depths so that the pile foundation positioning device can be horizontal.

[0024] The horizontal positioning mechanism 7 includes an installation cylinder 701, a fixing bolt 702, a fixing rod 703, an installation plate 704, a connecting rod 705, a laser lamp installation sleeve 706, and a laser lamp 707. The installation cylinder 701 is fixedly connected to the front outer wall of the guiding sleeve 3. The fixing bolt 702 is fixedly connected to the left through hole of the installation cylinder 701. The fixing rod 703 is movably connected inside the installation cylinder 701. The installation plate 704 is fixedly connected to the lower wall of the side of the fixing rod 703 away from the installation cylinder 701. The connecting rod 705 is fixedly connected to the middle of the installation plate 704. The laser lamp installation sleeve 706 is rotatably connected to the outer wall of the connecting rod 705. The laser lamp 707 is fixedly connected to the lower side of the laser lamp installation sleeve 706. The laser lamp 707 in the laser lamp installation sleeve 706 is vertically downward under the action of gravity to guide the installation of the fixing mechanism 6. And the horizontal positioning mechanism 7 can be disassembled for convenient use.

[0025] The guiding wheel 8 includes a rotating disk 801, a second threaded rod 802, a fixing frame 803, and a rotating wheel 804. The second threaded rod 802 is threadedly connected inside the guiding wheel fixing frame 5. The rotating disk 801 is fixedly connected to the side of the second threaded rod 802 away from the guiding wheel fixing frame 5. The fixing frame 803 is fixedly connected to the front side of the second threaded rod 802. The rotating wheel 804 is fixedly connected inside the fixing frame 803. The rotating wheel 804 in the guiding wheel 8 can reduce the collision between the pile foundation and the guiding sleeve 3. The rotating disk 801, the second threaded rod 802, and the fixing frame 803 can move the rotating wheel 804 back and forth to limit pile foundations with different diameters, reducing the deviation of pile driving.

[0026] Working principle: When in use, place the pile foundation positioning device at the positioning position, then put one end of the fixing rod 703 away from the laser lamp 707 into the inside of the installation cylinder 701, and rotate the fixing bolt 702 to install the horizontal positioning mechanism 7 on the guiding sleeve 3. The laser lamp 707 always faces downward under the action of gravity. Turn on the laser lamp 707 so that the laser points in the vertical direction. At this time, rotate the rotating disk 603 by rotating the rotating grip 604. The rotating disk 603 drives the first threaded rod 602 to rotate in the fixed nut 2, and drive the conical positioning head 601 into the ground. According to the laser direction, control different fixing mechanisms 6 to drive into different depths to make the pile foundation positioning device horizontal. At this time, remove the horizontal positioning mechanism 7 to prevent damage. When installing the pile foundation, rotate the turntable 801 according to the diameter of the pile foundation to drive the runner 804 to move forward, so that the size of the middle position of the runner 804 conforms to the diameter of the pile foundation. Then place the bottom end of the pile foundation into the guiding funnel 4 to guide the pile foundation into the guiding sleeve 3. The runner 804 can reduce the collision between the pile foundation and the guiding sleeve 3 and reduce the loss of the pile foundation positioning device.
